Given an array and a value, remove all instances of that value in-place and return the new length.

Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory.

The order of elements can be changed. It doesn't matter what you leave beyond the new length.

Example:

Given nums = [3,2,2,3], val = 3,

Your function should return length = 2, with the first two elements of nums being 2.





var removeElement = function(nums, val) {
    while(nums.indexOf(val)!=-1){
        nums.splice(nums.indexOf(val),1)
    }
};
//100 ms
